The Ancient Crime of Insulting Majesty
Lese-majesty is a legal term for defaming a ruler that dates back to the Roman Empire. While it sounds like a modern political concept, it actually began as treason against the authority of the emperor.
The term comes from the Latin laesa maiestas, meaning injured majesty. It traveled through medieval French courts before landing in English law. Historically, this wasn't just about hurt feelings; it was a serious crime against the dignity of the state itself. Even today, several countries use these archaic laws to penalize citizens who criticize their leadership.
